Differential pressure transmitter is a type of transmitter that is more widely used in the field of industrial automation, and the working principle of different models and types of differential pressure transmitters is also different, today we will introduce the working principle of different types of differential pressure transmitters in detail.
CCY11 micro differential pressure transmitter adopts piezoresistive pressure sensor chip, which uses the thin film resistance on the substrate for zero point correction, zero point temperature compensation and sensitivity compensation, and high-performance and stable silicon chip packaging, which makes it have high static pressure resistance, anti-interference, stability and reliability. Therefore, the CCY11 differential pressure transmitter can be applied to the micro differential pressure occasions for various gas measurements.
CCY15 differential pressure transmitter is to diffuse a Wheatstone bridge on a monocrystalline silicon wafer, and the pressure of the measured medium (gas or liquid) changes the resistance value of the bridge wall (piezoresistive effect) to generate a differential voltage signal, which is converted into a standard analog signal or digital signal by a special amplifier and the signal corresponding to the range.
CYYZ3051Differential pressure transmittersIt is an intelligent differential pressure transmitter. The smart circuit board of the CYYZ3051 differential pressure transmitter uses advanced integrated circuit and SMT technology to concentrate the conversion circuit and processing circuit on one circuit board. The microprocessor of the CYYZ3051 differential pressure transmitter controls the work of the A/D and D/A conversion modules, as well as the digital communication and self-diagnosis functions. During operation, the microprocessor controls the A/D conversion module to convert the analog signal from the sensitive element and convert it into a digital signal. Microprocessors process digital signals, including signal linearization, temperature compensation, engineering unit conversion, and more.
